[image]Colorimetric Solid-Phase Extractor - NASA/Marshall Space Flight Center
The heart of a colorimetric solid phase extractor (CSPE) test kit quickly measures the concentration of the biocides silver or iodine in astronauts? drinking water to determine whether concentrations are safe. When 10 milliliters (ml) of water is drawn through the disk, the disk will turn color (yellow in this picture for iodine) indicating the presence of the biocides. The device could someday be used to test water safety at reservoirs and water treatment plants on Earth...

[image]John Robinson Pierce, Communication Satellite Pioneer - NASA
John Robinson Pierce, the former director of research at AT&T Bell Telephone Laboratories. Born in Des Moines, Iowa in 1910, Pierce was the first to evaluate the various technical options in satellite communications and assess the financial prospects. In 1952, he published an article in Astounding Science Fiction in which he discussed the potential benefits of satellite communications. A few years later, Pierce greatly assisted in the creation of the first artificial communication satellite, ECH...

[movies]Polar Visible Aurora: High Solar Wind Conditions on April 17, 1999 over the North Pole - NASA/Goddard Space Flight Center Scientific Visualization Studio
On May 11, 1999, the solar wind that blows constantly from the Sun virtually disappeared. Dropping to a small fraction of its normal density and to half its normal speed, the solar wind died down enough to allow physicists to observe particles flowing directly from the Sun's corona to Earth. This severe change in the solar wind also drastically changed the shape of Earth's magnetic field and produced a rare auroral display at Earth's North Pole...

[movies]Polar Visible Aurora: North Pole Comparison between May 11, 1999 and November 13, 1999 (Continents) - NASA/Goddard Space Flight Center Scientific Visualization Studio
On May 11, 1999, the solar wind that blows constantly from the Sun virtually disappeared. Dropping to a small fraction of its normal density and to half its normal speed, the solar wind died down enough to allow physicists to observe particles flowing directly from the Sun's corona to Earth. This severe change in the solar wind also drastically changed the shape of Earth's magnetic field and produced a rare auroral display at Earth's North Pole...

[image]Fires and burn scars in central United States - Jacques Descloitres, MODIS Rapid Response Team, NASA/GSFC
With the return of the growing season, fires are beginning to appear all over the United States. These true- and false-color images, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on April 2, 2005, show the fires, which are marked in red, scattered across the states of Nebraska, Iowa, Kansas, Missouri, Oklahoma, and Arkansas (from right to left in rows, top to bottom)...
